Some change to the curve and posting/curation split may help matters, but it should not penalise small accounts too much. We know the orcas and whales do well from curation. Then again the system should discourage creating masses of small accounts. It's a tricky one to get right and you will never please everyone. Maybe it could be a variable system that adapts to deal whatever ways people try to game it, but then there will be lots of strategies going on.
One thing that should change is that rep should go up slower if all votes come from the same few accounts. We have people with really high rep just from buying votes, so it is meaningless.
